To aZZ whom it may concern:

Be it known that 1, ROBERT F. Ponce, a citizen of the United States,residing at Spiceland, in the county of Henry and State of Indiana, haveinvented certain new and useful Improvements in Step-Ladders; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to step ladders of that class which are adaptedto be extended.

The purpose of the invention is simplicity, efficiency and safety to theperson using it, as well as convenience in adapting the device for usein its ordinary or extended position.

The improvement consists essentially in a casting at the upper end ofthe brace section having a transverse slot and retaining notches nearthe ends of the said casting, and a staple to work in connection withthe said casting to secure the brace section in either of its twopositions.

The improvement further consists of the novel features and the peculiarconstruction and combination of the parts which will be hereinafter morefully described and claimed and which are shown in the annexed drawings,in which;

Figure l is a perspective view of a step ladder embodying my invention.Fig. 2 is a central longitudinal section of the ladder showing itextended, parts being broken away. Fig. 3 is a detail view of amodification.

The ladder A is of usual construction and the brace section B which isprovided with treads I), is connected with the sides of the ladder bymeans of the castings D and the staples O. The castings D, one for eachside piece of the brace section B, are fastened to the said side piecesin any convenient manner, and each is provided with a transverse slot (Zand with retaining notches e and f near the ends of the casting.The'castings are T shaped and the slot d is formed in the cross head E.

In Figs. 1 and 2 the notch e is formed in the under side of the crosshead and the notch tion is turned up as shown in Fig. 2, the upperportion of the staple will enter the notch f and the said section willrest bracingly against the top step of the ladder A. The

hook g and the eye it serve to hold the brace section B in an extendedposition.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut is;

1. A step ladder comprising the ladder A, and the brace section Bprovided with treads, castings secured to the side pieces of the bracesection and having transverse slots and notches e and f, and staples 0provided on the side pieces of the ladder A and adapted to engage withthe said castings, substantially as set forth.

2. In a step ladder the combination with the ladder and the bracesection, of castings secured to the sides of the brace section andhaving T-heads which are slotted and provided with notches c and f, andthe staples O secured to the side pieces of the ladder and adapted toengage with the said T-heads, substantially as described.

3. In a step ladder the combination with the ladder and the bracesection, of castings secured to the sides of the brace section andhaving T-hcads which are slotted, and having notches e and f at the endsof the said slots which extend in opposite directions therefrom andstaples C secured to side pieces of the said ladder and adapted toembrace a portion of the said T-heads, substantially as shown and forthe purpose specified.
